有谁知道android上应用程序管理器的包名。我有一种方法,我想让用户直接从我的应用程序转到应用程序管理器:
public void goToApplicationManager(){
Intent startMain = this.getPackageManager().getLaunchIntentForPackage("com.android.settings.ManageApplications");
startActivity(startMain);
}
但这会引发错误.. 我可以做 com.android.settings,它会将用户带到设置,但我想将它们专门带到应用程序管理器。我有错误的包名吗?
我的错误:
